Researchers at Max Planck Institute for the Science of Light and Friedrich Alexander University in Erlangen, Germany have recently demonstrated that a molecule can be turned into a coherent two-level quantum system. In their ...

Scientists at Tokyo Institute of Technology have fabricated a multiplexer/demultiplexer module based on a property of light that was not being exploited in communications systems: the optical vortex. Such devices will be ...

A new study published February 28 on arXiv.org suggests that a millisecond pulsar known as PSR J0740+6620 has a stellar companion. The research provides evidence indicating that this object is most likely accompanied by an ...

Some of the most advanced communication systems now under development rely on the properties of quantum science to store and transport information. However, researchers designing quantum communication systems that rely on ...

Optical coherence tomography (OCT) is a light-based imaging technique currently used in clinical diagnostics to examine organs in vivo. The technique uses interferometry; in which light reflected from an examined object combines ...

The optically guided bus is the latest in a long line of initiatives to repackage the bus as premium rail-derived technology. The name "trackless trams", the vehicle design, and the modest deployment costs all have broad ...

How long can tiny gears and other microscopic moving parts last before they wear out? What are the warning signs that these components are about to fail, which can happen in just a few tenths of a second? Striving to provide ...

Scientists at the RDECOM Research Laboratory, the Army's corporate research laboratory (ARL) have found a novel way to safeguard quantum information during transmission, opening the door for more secure and reliable communication ...

A new optical modem, capable of sending high-definition quality video significantly faster than standard radio frequency systems, is being developed for NASA's Orion spacecraft. The hardware, offered by LGS Innovations, is ...
